Estimation and Study on Forest Water Conservation Ecological Benefit

Abstract:

By using Ecological Observatory Station survey data and Landsat-5 TM remote sensing image data in 2008 as the basic data to construct the conventional multivariate statistical model. The determination coefficient of regression model was 0.788 and the average test accuracy was 81.1%. By using the parameters of this model as the input data to Geographic Information System (GIS) to reveal the spatial distribution of quantity and value, then estimated the total forest water conservation quantity of Laoshan in 2008, I = 263.78 tons, established the currency structure model of the study area to estimate the total value quantity of water conservation effective, E = 1.3189 million yuan. And then analyzed the variation feature of quantity change with topographical, also, the variation fits the truth.
